In block copolymer (BCP) nanolithography, microphase separated polystyrene‐block‐polydimethylsiloxane (PS‐b‐PDMS) thin films are particularly attractive as they can form small features and the two blocks can be readily differentiated during pattern transfer. However, PS‐b‐PDMS is challenging because the chemical diffe…

We investigate a two-orbital model for iron-based superconductors to elucidate the effect of interplay between electron correlation and Jahn-Teller electron-phonon coupling by using the dynamical mean-field theory combined with the exact diagonalization method. When the intra- and inter-orbital Coulomb interactions, $…

LaOBr:Nd(3+) nanofibers and nanobelts were synthesized for the first time via calcinating the electrospun PVP/[La(NO3)3 + Nd(NO3)3 + NH4Br] composites. X-ray diffraction (XRD) analysis revealed that LaOBr:Nd(3+) nanofibers and nanobelts are tetragonal in structure with the space group of P4/nmm. The morphologies and s…

In this study, we grew ZnO nanowires hydrothermally on (1-102) r-plane sapphire substrates in an aqueous solution which contained zinc nitrate hexahydrate and hexamethylenetetramine (HMT) at 90 °C. First, the AZO seed layer of 80 nm thickness was deposited on the r-plane sapphire substrate by a radio frequency magnetr…

We investigated the resonance frequency distributions of carbon nanotube (CNT) oscillators with an intertube gap using molecular dynamics simulations. The resonance frequency distributions could be regressed by the use of Gaussian distributions. The maximum resonance frequencies linearly decreased with increasing init…

The modification of catalysts with ionic liquids represents a development that combines both homogeneous and heterogeneous catalysis. This achievement is especially described by three different concepts: SILP, SCILL and nanoparticles in IL. SILP refers to the case where a metal complex is dissolved in an ionic liquid…

Thiols can diffuse and form self-assembled monolayers (SAMs) on the gold surfaces covered with polydimethylsiloxane (PDMS) stamps. For the first time, with cells as the indicator of how far alkanethiols had diffused to form SAM, we studied the growth dynamics of SAMs of HS(CH 2 ) 11 (OCH 2 CH 2 ) 3 OH (EG 3 ) and HS(C…
